not quite :) gnome-vfs2 still includes
/usr/lib/gnome-vfs-2.0/modules/libsmb.la. it also includes
/etc/gconf/schemas/system_smb.schemas, which should probably be in
gnome-vfs2-smb, though it could conceivably be in the main package too.
also, i just noticed that the files in /usr/lib/gnome-vfs-2.0/modules/
are owned by both gnome-vfs2 and gnome-vfs2-devel.
